Ilya is pissed

Regina's PoV

This has just turned for the worst. Onii-chan betrayed us...

While giving off a dazzling radiance, the White Dragon Emperor stood before us.

Beside him was the lady who was with Shizuku earlier. I believe Katerea Leviathan was her name.

"The instant you decided on peace, arrangements were made to invoke the Sacred Gear of the kidnapped half-vampire and begin the terrorist attack. The Hakuryuukou ran wild along with me once we saw a good time. It'd be good if we could bury any one of the leaders of the three greatpowers. It was fine if the meeting was broken because of that."

This is just great... I can't exactly fight Onii-chan in my current state right now. Father who noticed me looked concerned.

"You all right?" I asked him first with a bitter smile.

"Ive been better, I guess..." He replied with a bitter smile on his own. "Seems like you had a hard fight."

"Tell me about it... I was against freaking Yamata no Orochi." Hearing that shocked them especially Draig

[That is impossible, Yamata no Orochi should be dead.] Draig's voice resounded from the boosted gear.

"He is similar to you and Albion, sealed. However he is sealed within Kusanagi and it appears he became stronger than in the legends. He has obtained the power of [Extinction] as they called it." I explained.

As we were talking Issei was leering on Katerea Leviathan.

"I feel vulgar eyes. —Is this kid the Sekiryuutei, Vali?"

"Yeah, while regrettable, it's true. He truly is a most regrettable host."

"Don't keep saying regrettable, regrettable! Even I'm living through everyday doing my best! …Or rather, why are you and Azazel confronting each other? Or rather, who is this onee-chan?"

Katerea Leviathan looked at the babbling Issei with pitying eyes.

"I see. He really does seem to be a regrettable child. Vali, will you kill him?"

"My feelings are wavering on what to do. To be honest, I wasn't expecting for him to be there."

"Geez, I've also lost my edge. For one of my followers to do this…" said Father while looking lonely.

"Don't worry Father, Onii-chan is probably just on his rebellious phase." I said to Father which caused him to laugh.

"Vali, has the [Vanishing Dragon] capitulated to Ophis?" Father asked after calming down from his laughter.

"No, I'm just cooperating stubbornly. They gave an attractive offer.

'Wouldn't you like to fight against the Asgard?' When they said that, as someone who wants to test my power, I couldn't decline. Azazel, you dislike the idea of fighting with Valhalla—the Asgard, right? You dislike war."

"I told you to 'become strong', but I should have also said 'don't only make factors that will destroy the world'."

"That's unrelated. I just want to fight eternally."

"…I see. No, I may have anticipated somehow in my heart that you would leave my side. —Since the time we met till now, you wanted to fight with strong people."

"The preparations and information outlet for this were thanks to the Hakuryuukou. It's unusual of you to have left him alone even though you understood his true nature. As a result, you've wrung your own neck."

And so the lady sneered at Father which caused me to be annoyed. If this way before I fought Shizuka I would wipe the sneer off her face.

Ignoring Father who gave a bitter smile, Vali hit his hand against his chest and spoke to Issei.

"My real name is Vali. —Vali Lucifer."

Ignoring the shocked people he continued.

"I'm a descendent of the previous generation's Maou Lucifer who died. However, I'm a child of mixed blood born from a father who was the old Maou's grandson and a human mother. —I obtained the [Vanishing Dragon]'s Sacred Gear because I'm half-human. It was just by chance. However, I, who is a true blood relative of Lucifer and is also the [Vanishing Dragon], was born. If there really is such a thing as fate and miracles, I may be that. —Just joking."

As he said that, several folds of devil wings grew from his back along with his wings of light.

"No way…that can't be…"

Rias also wore an astonished expression on her face. However, Azazel confirmed it.

"It's true. If there is such a ridiculous existence, it's him. He'll become the strongest Hakuryuukou of among those I knew in the past and present, and probably of all time as well."

"Then isnt my and Raina's existence also pretty ridiculous?" I said with a teasing smile.

"I mean we are descendants of you who is the strongest Fallen Angel along with Longinus class sacred gears even older than [True Longinus]. So dont be afraid of Onii-chan, Issei so what if he is Lucifer and the White Dragon Emperor. I am the King of Heroes and the Golden Princess of Regulus Dominion." I said trying to stand up.

"Regina... your in no condition to fight." Said Yuuto-kun who is holding on to me.

"So what? I have to bring back and scold Onii-chan... For Father..." I said before eventually losing my consciousness.

...

Ilya's PoV

Regina struggled wanting to bring back onii-chan for Father. However she eventually lost consciousness due to exhaustion which caused everyone to panic. She must have had a hard fight especially against someone like that woman Shizuku who used poison. She needed to keep her purifying aura at all times to avoid being poisoned.

"She is alright." I tokd them to alleviate their worries.

"[Avalon]" I created a copy of avalon and placed it inside Regina to help her recover. Although it would disappear later on It should still last for a while.

"Father..." I looked towards the injured Father. As I also proceed to created another avalon to heal him.

"He he, Dont worry too much I am still fine."

As we were talking the lady beside Onii-chan asked Father.

"Have you resolved yourself, Azazel?"

The lady sneered at the injured Father. Who is this person? I want to skin her alive...

"…Tch, that volume of aura that swelled up earlier, what did you get from that bastard Ophis?"

The lady smiled at Father's question.

"Yes, he who is the dragon that possesses infinite power. For the sake of the world's reformation, I borrowed a little of his power. Thanks to that I can fight against you. There's even a chance that I can beat Sirzechs and Michael. They're such foolish Leaders. So are you."

"Father, permission to slaughter her." I asked Father with looking at this lady with a cold expression.
